Writing in CamelCase-format consists in joining together words without spaces and capitalizing each word within the compound: HomePage, PageIndex, WikkaWiki are all examples of CamelCase words. The name comes from the uppercase "bumps" in the middle of the compound word, suggesting the humps of a camel.

Some words like MySQL, McCain are represented using a camelcase format. If you write them in a page, the word automatically links to the page of that name, if such page exists, or to an edit screen where you can create it if it doesn't yet exist. To avoid this behavior, you may surround the word inside double doublequote, like ""MySQL"".
